1. Well...
\n" ); document.write( "- \"%28a-b%29%5E2+=+a%5E2+-+2ab+-+b%5E2\" and likewise...
\n" ); document.write( "- \"%28a%2Bb%29%5E2+=+a%5E2+%2B+2ab+%2B+b%5E2\"
\n" ); document.write( "2. So simply plug in your equation
\n" ); document.write( "- \"%282y-3%29%5E2\"
\n" ); document.write( "- \"a+=+2y\" and \"b+=+3\"
\n" ); document.write( "- \"%28a-b%29%5E2+=+a%5E2+-+2ab+-+b%5E2\" (The stuff on the left side isn't included in the formula i'm just leaving it over there for now to show you where i got the values from
\n" ); document.write( "- \"%282y-3%29%5E2+=+%282y%5E2%29+-+2%282y%29%283%29+-+%283%29%5E2\"
\n" ); document.write( "3. Finally simplify
\n" ); document.write( "- \"%282y%5E2%29+-+2%282y%29%283%29+-+%283%29%5E2\"
\n" ); document.write( "- \"%282%5E2%29%28y%5E2%29+-+12y+-+9\"
\n" ); document.write( "= \"4y%5E2+-+12y+-+9\" And there's your answer
\n" ); document.write( "
\n" );
